DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a print medium for a printer, and more particularly to a print medium suitable for printing on cloth.

[0002]

2. Description of the Related Art In recent years, printing methods using ink-jet printing, which can easily produce a large variety of products in small quantities as compared with screen printing and roller printing, have been actively studied. However, it is difficult to use an ink jet printer that is currently used by offices and individuals for printing on paper and OHP sheets as it is for printing, and for that purpose, there are still many problems that need to be solved, and there is a need for improvement. .

[0003] That is, since the optimum color material structure and type differ depending on the type of cloth, the type of ink to be used must be changed for each cloth, and it is also used for conventional office and personal ink jet printers. The inks are designed to be printed on paper or OHP film, so if they are used as they are, the types of cloth that can be printed will be limited, and the color density after printing will be low. In the washing step after printing, the undyed portion was sometimes contaminated. Also, there is a problem that, unlike paper, a cloth having an unstable shape cannot be easily transported.

Conventionally, in order to solve problems such as transportability,
As a method of ink-jet printing on a cloth, a method of temporarily adhering a cloth on a non-stretchable flat support coated with an adhesive and printing with a printer (Japanese Patent Laid-Open No. 63-6183), a method using an adhesive, 2. Description of the Related Art A method of attaching a cloth to a sheet having an adhesive layer mixed with a migration inhibitor and performing ink-jet printing (Japanese Patent Laid-Open No. 2-68272) is known. These prior arts have been devised to improve the transportability of a cloth by a printer and to suppress irregular bleeding of ink during printing. However, these conventional techniques have not yet been able to provide a sufficient effect.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to limit the types of cloths on which printing is possible, and there is no need to change the ink used according to the type of cloth. Print media that can be applied to ink jet printers as they are, provide a high color density after printing, and provide a practical printed material that does not cause contamination of undyed portions due to the water washing process after printing. , And an inkjet printing method using the same.

It can be printed in the size of a plate or the like and printed like ordinary paper or OHP, or can be rolled and printed continuously.

A preferred method and apparatus for performing printing using the printing medium of the present invention include, for example, applying thermal energy to ink in a chamber of a head in response to a signal, and using the thermal energy to form ink droplets. And a method for generating the same.

FIGS. 1, 2 and 3 show examples of the configuration of a head which is a main part of the apparatus.

The head 13 includes a glass, ceramic or plastic plate having a groove 14 through which ink passes, and a heating head 15 used for thermal printing (a head is shown in the figure, but is not limited to this). And obtained by bonding. The heating head 15 includes a protective film 16 made of silicon oxide or the like, and aluminum electrodes 17-1 and 17.
-2, a heat-resisting layer 18 made of nichrome or the like, a heat storage layer 19, and a substrate 20 having good heat dissipation such as alumina.

The ink 21 has a discharge orifice (fine hole) 2
2, and the meniscus 23 is formed by the pressure P.

Here, when an electric signal is applied to the electrodes 17-1 and 17-2, the area of the heating head 15 indicated by n rapidly generates heat, and bubbles are generated in the ink 21 in contact with the area. The meniscus 23 protrudes due to the pressure, the ink 21 is ejected, and the ink droplets 24 form the orifice 22 and fly toward the print medium 25.

FIG. 3 is an external view of a multi-head in which many heads shown in FIG. 1 are arranged. The multi-head is manufactured by closely contacting a glass plate 27 having a multi-groove 26 and a heating head 28 similar to that described with reference to FIG.

FIG. 1 shows a head 1 along an ink flow path.

FIG. 4 shows an example of an ink jet printing apparatus incorporating such a head.

In FIG. 4, reference numeral 61 denotes a blade as a wiping member, one end of which is held by a blade holding member and serves as a fixed end, forming a cantilever. The blade 61 is disposed at a position adjacent to a print area by the head, and in this example, is held in a form protruding into the movement path of the head. Reference numeral 62 denotes a cap, which is disposed at a home position adjacent to the blade 61, and has a configuration in which the cap moves in a direction perpendicular to the moving direction of the head to abut on the discharge port surface to perform capping. Further 63

With these configurations, the print medium is fed to a position facing the discharge port surface of the head, and is discharged to a discharge section provided with discharge rollers 53 as printing proceeds.

In the above configuration, when the head 65 returns to the home position at the end of printing or the like, the cap 62 of the head recovery unit 64 is retracted from the moving path of the head 65, but the blade 61 protrudes into the moving path. As a result, the ejection port surface of the head 65 is wiped. When capping is performed with the cap 62 in contact with the ejection surface of the head 65, the cap 62 moves so as to protrude into the moving path of the head.

When the head 65 moves from the home position to the print start position, the cap 62 and the blade 61 are at the same positions as those at the time of wiping described above. As a result, the ejection port surface of the head 65 is also wiped during this movement.

The above-mentioned movement of the head to the home position is performed not only at the end of printing or at the time of ejection recovery, but also at a predetermined interval to the home position adjacent to the printing area while the head moves through the printing area for printing. The wiping is performed along with the movement.

FIG. 5 is a view showing an example of an ink cartridge containing ink supplied to the head via an ink supply member, for example, a tube. Here, reference numeral 40 denotes an ink storage portion that stores the supply ink, for example, an ink bag, and a rubber stopper 42 is provided at the tip thereof. By inserting a needle (not shown) into the stopper 42, the ink in the ink bag 40 can be supplied to the head. 44
Is an absorber that requires waste ink. As the ink supply unit, a unit whose liquid contact surface with the ink is formed of polyolefin, particularly polyethylene, is preferable for the present invention. The ink jet printing apparatus used in the present invention is not limited to the one in which the head and the ink cartridge are separated as described above, but may be suitably used in an integrated one as shown in FIG.

In FIG. 6, reference numeral 70 denotes a printing unit, in which an ink storage portion for storing ink, for example, an ink absorber is stored, and the ink in the ink absorber has a plurality of orifices. Head part 7
It is configured to be ejected from 1 as ink droplets. It is preferable to use polyurethane as the material of the ink absorber. Reference numeral 72 denotes an atmosphere communication port for communicating the inside of the print unit with the atmosphere. This print unit 7
Numeral 0 is used in place of the head shown in FIG. 4, and is detachable from the carriage 66.

The printed medium to be printed is heated if necessary, then washed with water, and the fabric is peeled off from the substrate and dried. Alternatively, a printed matter is obtained by peeling the fabric from the substrate after drying.

The obtained printed matter is cut into a desired size as necessary, and the cut pieces are subjected to a process for obtaining a final processed product such as sewing, bonding, welding and the like. Thus, processed products such as ties and handkerchiefs can be obtained.
